Embodiment Construction

[0015] An embodiment of the present invention has a box, which is a mounting accessory for a circuit breaker, having terminals connected to main power lines through a power distribution device mounted on the box. There are two baffles on the back of the box, the purpose is to cover the terminals to prevent the circuit breaker from contacting the working terminals when it is withdrawn. The bezel rises to allow easy and quick connection of the retractable circuit breaker to the terminals.

[0016] In one embodiment, the fender is locked in place by a fender lock member consisting of two strip metal pieces, wherein the metal pieces are provided with hook structures and are connected to the fender. The bezel lock has access hooks on the keyhole structure, which facilitates assembly and removal of the bezel lock, and prevents the bezel lock from moving in the direction of opening the bezel. The other end of the hook of each baffle lock has a round hole to accept a padlock with a s...

Abstract

The invention discloses a box (100) used in extraction type breaker equipment. The box (100) includes a basal part with an exterior edge (99) and a rear edge (96), the rear edge limits back, one group of baffles (105, 110) are set on back and are configured to open and close, and one group of baffle locks (115, 120) extend from the exterior edge (99) to the rear edge (96) and is operable coupled with one group of locks (105, 110). Therein, the baffle locks (115, 120) bias press to first position, and is driven to second position response to the baffle locks (115, 120), the baffles (105, 110) opening is prevented. The baffle locks (115, 120) are configured to being limited in second position.

Description

technical field [0001] The present invention generally relates to a withdrawable circuit breaker and particularly relates to the arrangement of a shutter lock of a withdrawable mechanism (here referred to as a box) of an air circuit breaker. Background technique [0002] The box is the fixed accessory within which the circuit breaker is installed, which has terminals connected to the main power lines. The box has baffles covering the terminals to prevent contact with the working ends when the circuit breaker is retracted. The baffle can also be raised: allowing the retractable unit (circuit breaker) to be easily and quickly connected to the terminals of the box. It is customary to use the bracket mechanism to install or move the circuit breaker from the box. Many enclosures utilize bezel locks, which are located close to the terminals as ancillary equipment, or the bezel lock's front panel, which contains many components, which add complexity and cost to the enclosure's as...
